This article considers the exploitation of parasitic antenna arrays in multi-user (MU) wireless communication systems by using their adaptive beamforming capabilities in order to improve the average system throughput. The use of parasitic arrays and especially the electrically steerable passive array radiator (ESPAR) antennas enables the design of terminals with a single RF front-end and reduce...

In this paper, we explore the quantitative investigation of the high-frequency performance of Gate Electrode Workfunction Engineered (GEWE) Silicon Nanowire (SiNW) MOSFET and compared with Silicon Nanowire MOSFET(SiNW MOSFET) using device simulators: ATLAS and DEVEDIT 3D. Simulation results demonstrate the improved RF performance exhibited by GEWE-SiNW MOSFET over SiNW MOSFET in terms of transc...

A brief review of the main physical results about the low temperature characterization and modeIing of Si CMOS devices is presented. More specifically, the carrier mobility law. the saturation velocity, the short channel effects, the impact ionization phenomenon. the hot carrier effects or the parasitic leakage current are physically discussed.

The calcium-gated potassium channel SLO-1 in Caenorhabditis elegans was recently identified as key component for action of emodepside, a new anthelmintic drug with broad spectrum activity. In this study we identified orthologues of slo-1 in Ancylostoma caninum, Cooperia oncophora, and Haemonchus contortus, all important parasitic nematodes in veterinary medicine. Furthermore, functional analyse...

The prevalence of human and animal helminth infections remains staggeringly high, thus urging the need for concerted efforts towards this area of research. GABA receptors, encoded by the unc-49 gene, mediate body muscle inhibition in Caenorhabditis elegans and parasitic nematodes and are targets of anthelmintic drugs. Thus, the characterization of nematode GABA receptors provides a foundation f...

for the purpose of modeling modern VRM, parasitics of VRM must be fully characterized. This paper presents experiment methods to characterize fast switching modern VRM. Results of parasitics, including inductance and resistance, of fast switching VRM are provided. Introduction Modern voltage regulator modules (VRM) for microprocessors have developed to a very high efficiency, very high current ...

The ram's horn snail (Planorbella trivolvis (Say)) is an intermediate host for a digenetic trematode (Bolbophorus confusus (Krause) Dubois) that has recently been discovered to be a significant problem in commercial channel catfish (Ictalurus punctatus Raf) production ponds in the Mississippi Delta region in the USA. In these catfish ponds, the digenetic life cycle of this parasitic trematode i...

Changes in the stream flow contribute to transformation of river channel due erosion and accumulation. Channel bars move as a result water flow. This article presents results studies carried out on two formed River Vistula that were transformed during emergency discharges from Włocławek reservoir. In order present changes structure texture, pits dug samples taken for grain-size analysis. The ra...
